Lnkfora/ ig/M w MM ATTORNEYS United States Patent 2,776,463 FLOOR BEAM RECESS FORM FOR FOUNDATIONS Arman L. Lankford, Modesto, Calif. Application November 28, 1952, Serial No. 322,849 2 Claims. (ems-11s This invention is directed to, and it is a major object to provide, a novel metallic, re-usable device for forming a pocket or recess in the upper portion of a foundation for the reception of an end of a floor beam.

Another important object of the present invention is to provide a form device, for the purpose described, which comprises a box-like metallic body and hook means for engagement with, and nailing to, the topmost inner form board, whereby to properly suspend and position the device for pouring of the foundation thereabout.

An additional object of the present invention is to provide a form device, as in the preceding paragraph, wherein the metallic box-like body comprises right and left hand sections having lapping portions, and there being means included in the device to contract the body by pulling the sections towards each other so as to aid in breaking the device free and removing it from the foundation after the latter is set.

It is also an object of the invention to provide a form device which is designed for ease and economy of manufacture, and convenience of use; the device being strong and durable, and capable of long service without replacement.

Still another object of the invention is to provide a practical and reliable form device, and one which will be exceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings:

Fig. l is a perspective view of the form device.

Fig. 2 is a sectional plan on line 2-2 of Fig. 1.

Fig. 3 is a sectional elevation of the device as in use.

Fig. 4 is a diagrammatic view of a foundation as poured between form boards and showing one of the devices as in use.

Fig. 5 is a similar view, but shows the foundation after removal of the form boards, and with the form device contracted but before its removal.

Fig. 6 is a similar view, but shows the recess of pocket after the device is removed; a floor beam being shown in dotted lines as seated in such recess.

Referring now more particularly to the characters of reference on the drawings, the form device comprises a relatively small, box-like form fabricated from sheet metal; such form being open at the top and front.

The box-like form 1 comprises side plates 2, lapping relatively slidable back plates 3, and lapping relatively slidable bottom plates 4; the lap of the back plates 3 being shown at 5, and the lap of the bottom plates 4 being shown at 6.

As so constructed, the box-like form 1 comprisesin etfect-right and left hand sections, with lapping portions adapted to be relatively slidably adjusted inwardly ice or outwardly whereby to contract or expand the form, respectively. This is accomplished as follows:

The side plates 2 are fitted, on the inner face, with a laterally inwardly projecting boss 7; the bosses 7 being axially alined and tubular.

A cross rod 8 extends between the bosses 7, and at opposite ends such rod is threaded into the related bosses with right and left hand threads, respectively. Thus, with rotation of the cross rod 8 in one direction the box-like form 1 is contracted, whereas rotation in the opposite direction expands the form. Rotation of the cross rod 8 is facilitated by means of holes 9 which extend diametrally through such rod, and which holes are for the reception of a manually actuated turning bar or In addition to serving as the adjusting means for the form 1, the, cross rod 8 connects the right and left hand sections against undesirable separation.

Adjacent the upper front corners thereof each side plate 2 is fitted with a normally forwardly projecting, downwardly opening hook 10; such hooks being of generally inverted U-shape, and each being formed in the forward leg by a plurality of holes 11. The rearward legs of such hooks are pivoted, as at 10a, to the side plates 2.

Prior to the pouring of a foundation 12 each form device, as above described, is suspended in proper position by engaging the hooks 10 over the uppermost one of the inner form boards 13; the outer form boards being shown at 14. See Fig. 4.

Nails 15 are driven through the holes 11 into the uppermost one of the inner form boards 13, whereby to exactly locate the form 1; the latter having inclined forward front edges on the side plates 2 which matchingly engage the inner form boards 13 when the latter are mounted at a slope. In those instances where the inner form boards 13 are vertical, then the form 1 has the front edges of the side plates 2 likewise vertical.

With the form 1 supported from the uppermost one of the inner form boards 13, as in Fig. 4, the foundation 12 is then poured betweenthe boards 13 and 14.

After the foundation 12 has set, the nails 15 are pulled; the hooks 10 swung rearwardly about the pivots ltla until they clear the uppermost one of the inner form boards 13, and then theboards 13 and 14 are stripped from the foundation.

After such boards are stripped away from the foundation the cross rod 3 is rotated in a direction to contract the form 1 in the manner shown in Fig. 5.

After the form is so contracted it can be readily broken away and removed, from the foundation 12, leaving a well formed recess 16 (see Fig. 6) for the reception of one end of a floor beam 17.

While simple and yet rugged in structure, the described recess form is very practical and reliable for the intended purpose, and can be used over and over in connection with form boards to provide floor beam recesses in poured foundations.

From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:

1. A floor-beam recess form for a foundation to be poured between the confining boards of a foundation form; said recess form comprising a box-like body including sidewalls adapted to abut along their forward edges against the inner face of one of the form boards, hooks projecting upwardly from the inner face of the sidewalls and adapted to engage over the top of said board is normally clearance relation thereto, means to detachably secure the hooks on their outer side to the one form board in body supporting relation, and means pivoting the hooks on the sidewalls for upward and rearward movement from a board engaging position; the hooks being shaped so that upon such upward swinging movement thereof, said hooks will clear the board.

2. A floor-beam recess form for a foundation to be poured between the confining boards of a foundation form; said recess form comprising a box-like body including sidewalls adapted to abut along their forward edges against the inner face of one of the form boards, and hooks projecting upwardly from and mounted on the sidewalls in position to overhangsaid form board and including straight relatively long depending portions arranged to extend downwardly on the outside of and adjacent the board and being then parallel to the forward edges of the sidewalls whereby the recess form may be vertically adjusted on the board while still remaining hook-engaged therewith; said hook portion being provided with holes to receive nails whereby to detachably secure the hooks on the board in any desired position of adjustment on said board.
